11 sec. build cost?

The only thing keeping me from turning my dart into a 11 sec. is that I really like driving it around. I don't drive it anywhere more than 10 miles away usually but I drive it a few times a week. I am graduating from college in May though and am hoping to get a little cash for that. So my options are pull the motor out and put new flat tops in it and some heads and maybe bore it out and put it back in the dart and see where I am at with that. Or look for a cheap mopar maybe even a roller that someone started to turn into a race car and just build another drive train. I am pretty sure the transmission I have in the car now would be fine for 11 second passes, I might up the convert and add a reverse valve body but it already has a B&M flexplate and 3000 rpm convert in it now.
